Version: 3.0
Timing DP-Cycle
...: Shows the timing of the DP cycle; this is particularly advantageous when
StartUp-/Fault-Settings

.
Firmware
: Displays the current FC310x firmware version.
Firmware Update
...: This command can be used to update the FC310x card firmware.
Hardware Configuration
...: The hardware version number of the FC310x can be displayed here
Upload Configuration
...: The PROFIBUS is scanned with this command, and all the devices found are
added to the FC310x device. (A box may not be added in TwinCAT 2.8; as from TwinCAT 2.9 scanning can
also take place even when boxes are inserted. The FC310x then accepts the new configuration, but does
show changes). In the case of Beckhoff boxes, the configuration is read precisely. In the case of external
devices, the corresponding GSD file will be searched.
Verify Configuration
...: This causes the PROFIBUS to be scanned and compared with the currently
inserted boxes. Changes are displayed (from TwinCAT 2.9).

Slot-Time
: The Slot-Time indicates how long the DP master will wait for a response from the DP slave
before it sends either a repetition or the next telegram.
min. Tsdr
: The min. Tsdr indicates the minimum length of time for which the DP slave will wait with a
response. This time is set for all the DP slaves during the DP start-up (the value range is 11-255 bit periods).
The min. Tsdr must be smaller than the max. Tsdr.
max. Tsdr
: The max. Tsdr indicates the maximum length of time for which the DP slave may wait with a
response. This time is set according to the DP slave's GSD file entries. The max. Tsdr must be smaller than
the slot time.
GAP-Factor
: The GAP factor determines how often the GAP update will be carried out (assuming it is
activated). The time between two GAP updates cycles is
Gap-Factor * Target-Rot.-T
